I agree that those are two contrasting approaches operating under different principles. Thus, 100% of the heat is transferred. * Free slots for orders with water heaters, boilers and other bulky items onlyI'm sorry, your email address was not found in our system.This product does not comply with the Safe Drinking Water Act, which requires that products used in any system providing water for human consumption (drinking or cooking) to meet low-lead standards. L4006A,B,E,H AQUASTAT® CONTROLLERS 60-0915—5 4 OPERATION For proper selections of settings, follow boiler manufacturer recommendations: 1. If NOT, then I need to raise the Low Limit NOT the Differential. But with a little thought, we can adjust these HI LO DIFF settings and thus set the heating aquastat control so as to save a bit more on heating cost, and/or we can set the control to give us a bit more hot water where a tankless coil is installed.Then when your bath tub still doesn't have but a few inches of hot water,It's not hard to understand why heating service techs and homeowners are confused about LO and DIFF settings on a heating boiler, but Honeywell got it right: if we are making hot water with a tankless coil, by locking out the circulator at lower boiler temperatures, the LO and DIFF make sure that heating priority is given to the woman in the shower, not to the building radiators.In our photo at left you'll see where the heating service tech left this "LO" limit control after cleaning and tuning the heating boiler.In other words, hotter water actually transfers heat into the occupied space more efficiently than cooler water.The photo above shows a the "HIGH" or "HI" setting on a Honeywell R8124A combination heating control, also called an "aquastat".
The circulator will not turn on even though the oil gun is turned off by the wood/coal boiler. First, the faucet in our bath tub/shower is the Delta single knob that adjusts both temperature and flow.That said, and if that's the case....is that coil conducive to repair (Soldering, brazing, etc) ?
This works exactly like another zone with the âthermosetâ that call for heat as part of the SuperStor. Water boils at 212 F. WATCH OUT for a BLEVE boiler explosion (search InspectAPedia for BLEVE explosions for details)You made your boiler hotter which will give more heat to the tankless coil in the boiler, but if the tankless coil is clogging or clogged that will reduce the hot water pressure or flow rate - though not the total quantity of hot water.The LO and DIFF are almost irrelevant to this operation and use, and that may be why your tech disabled that circuit. Because a mistake can burn down the house or cause other unsafe conditions, I figure if your heating service technician deliberately disabled something she must have thought it was unsafe.
